Now that the day of departure is getting closer I'm coming up with some - perhaps - silly questions but as this will be my first non-European Union flight there are a few new things I've never been through, such as the immigration control, and I always like to know previously what to expect upon arriving at a place.

So, after leaving the aircraft what comes first? Immigration control, luggage claim and then customs - is this the correct order? I read there's fingerprinting and photographing at immigration control, do passengers on the Visa Waiver Program pass through this process too?

My mother does antihypertensive and antihypercholestherolemic medicines and - ocasionally - an anxiolytic (Xanax) - are these medicines OK or are likely to be seized at customs?
